one fang

A character with a single visible canine tooth — in many cases, this is the only tooth visible — however, in most cases, the character is assumed to have a full set of teeth and a matching fang.
Often seen in kemono art and other anime/manga inspired art styles. "Single fangs" are typically added for the sake of cuteness, and are also frequently used to suggest mischievousness.
